  • the ornamental films (4-layer composite films with liner) prepared in Examples 1 to 26 and in Comparative Examples 1 to 6 were cut into test pieces measuring 25 mm ⁇ 70 mm. PET liners were peeled off the test pieces. Thereafter, each test piece was stuck to the horizontal surface of the coating plate 20 with the base member on the lower side as shown in FIG. 2(B) . Next, as shown in FIG. 2(C) , the test piece 10 was pushed onto the recessed portion 21 of the coating plate 20 so as to go along the curved surface of the recessed portion 21 .
  • test pieces In sticking the test pieces, those test pieces are represented by O when they could be intimately adhered and stuck onto the curved surface of the recessed portion 21 without developing such inconveniences as cut or cracks in the ornamental film, and are represented by X when they could not be intimately adhered and stuck onto the curved surface of the recessed portion 21 due to the occurrence of wrinkles during the sticking operation.
  • the results of evaluation were as described in Table 1 below.
  • the scratch resistance can be markedly improved as compared to the conventional technology. As compared to when the base member is blended with the spherical fine filler particles, further, the scratch resistance can be achieved to a comparatively satisfactory degree despite of a small blending amount. The scratch resistance can be further improved with an increase in the amount of blending the non-spherical fine filler particles.
  • the three-dimensional curved surface follow-up property can be markedly improved as compared to the conventional technology.
  • the three-dimensional curved surface follow-up property can be achieved to a comparatively satisfactory degree despite of a small blending amount.
  • a total of 17 kinds of ornamental films prepared in Examples 1, 2, 4, 7, 9, 10, 12, 15, 18, 20 and 22 to 26 and in Comparative Examples 1 and 2 were measured for their tensile modulus values in accordance with the procedure described below, and were evaluated.
  • the ornamental films were cut into test pieces measuring 10 mm ⁇ 100 mm. PET liners were peeled off the test pieces. Thereafter, each test piece was set to a tensile jig of a tensile testing machine (trade name: Tensilon UCT-100, manufactured by Orientech Co.), and was pulled at a rate of 200 mm/min. While continuing the pulling, a tensile stress (tensile modulus value) of when the test piece is stretched by 50%) was measured. A direction in which the reactive urethane coating solution was applied to the ornamental film was regarded to be the MD and the direction at right angles therewith was regarded to be the CD, and the tensile modulus values were measured in the respective directions. There were obtained the measured results as described in Table 2 below.
